Make a smooth paste of the grated coconut, 2 cloves of garlic, half of the ginger, 2 of the the green chillies, chilli powder and turmeric powder.
In a kadai, heat 2 tablespoons of coconut oil and temperature it with mustard seeds.
After the mustard seeds crackle,add the fenugreek seeds.
Immediately add the shallots and the remaining ginger and garlic, followed by the curry leaves. Stir fry till it is all slightly caramelised.
Add the mangoes and salt. Stir it well and let it cook for 10 minutes at a low flame or till the mangoes are soft.
Now add the prawns and stir well on a high flame.
As the prawns begin to change colour, add the coconut gravy. Add a little water too to adjust the consistency of the gravy.
On a reduced flame, allow this to cook well. Stir this in between.
The prawns take very less time to cook. Once it is done, pour a tbsp of coconut oil and garnish with a few curry leaves.

After the dish is cooked, 1/4 cup coconut milk can be added to the gravy and just stirred in. This makes the gravy more creamy.
